Over time, heat soak causes the thermoplastic housing to develop microscopic stress fractures, leading to secondary voltage leakage and internal dielectric breakdown. Coupled with high-mileage spark plug electrode erosion, the resulting high electrical resistance triggers hesitation under load, unburnt fuel washdown, and persistent Diagnostic Trouble Codes such as \u003cstrong\u003eP0300\u003c\/strong\u003e through \u003cstrong\u003eP0304\u003c\/strong\u003e.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis complete ignition refresh kit pairs a reinforced 4-cylinder coil rail with four precision-engineered iridium spark plugs. The replacement ignition cassette features high-grade dielectric epoxy potting to resist thermal degradation and internal short-circuiting, while premium silicone spark plug boots insulate against arcing. The matched fine-wire iridium spark plugs offer superior thermal tolerance and a lower required firing voltage compared to standard copper or nickel units. This configuration ensures an efficient, concentrated spark kernel across the entire RPM band, improving cold starts and fuel atomization.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; margin-bottom: 20px;\"\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eFitment\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e2002-2005 Chevrolet Cavalier\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eEngine \/ Chassis\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e\n\u003cstrong\u003e2.2L Ecotec L61\u003c\/strong\u003e \/ \u003cstrong\u003eGM J-Body\u003c\/strong\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eStock Output\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e140 hp \/ 150 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eReplaces OEM Part #\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e\n\u003cstrong\u003eUF391\u003c\/strong\u003e, \u003cstrong\u003e10458422\u003c\/strong\u003e, \u003cstrong\u003e12580538\u003c\/strong\u003e, \u003cstrong\u003e12587426\u003c\/strong\u003e, \u003cstrong\u003eGN10111\u003c\/strong\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2002-2005 Chevrolet Cavalier Base (2.2L L4 DOHC Ecotec)\u003c\/li\u003e\n  \u003cli\u003e2002-2005 Chevrolet Cavalier LS (2.2L L4 DOHC Ecotec)\u003c\/li\u003e\n  \u003cli\u003e2002-2005 Chevrolet Cavalier LS Sport (2.2L L4 DOHC Ecotec)\u003c\/li\u003e\n  \u003cli\u003e2002 Chevrolet Cavalier Z24 (2.2L L4 DOHC Ecotec)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the J-Body Cavalier?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2002-2005 Chevrolet Cavalier equipped with the \u003cstrong\u003e2.2L Ecotec L61\u003c\/strong\u003e engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAre the included iridium spark plugs pre-gapped?\u003c\/strong\u003e\u003cbr\u003e Yes, the plugs are factory gapped to OEM specifications, though verifying gap with a non-contact gauge before installation is standard practice.\u003c\/p\u003e\n\n\u003ch3\u003eThe Chevrolet Reliability Standard\u003c\/h3\u003e\n\u003cp\u003eThe \u003cstrong\u003eJ-Body\u003c\/strong\u003e platform is renowned for long-term commuter reliability when core powertrain components are correctly maintained.
